Abstract :
This paper reports on a high performance navigation grade MEMS servo accelerometer targeted at inertial applications. Reported results are for a bulk MEMS capacitive sensor with 11g full scale over a 300 Hz bandwidth interfaced with a highly optimized servo-loop 5th-order sigma-delta electronic. Measurements demonstrate a long-term bias stability of +/-0.2mg, a second order non-linearity K2 < 5 ¿g/g2, an in-band noise floor of 1 ¿g/¿Hz and a Dynamic Range over 1 Hz bandwidth of 22 bits.
